That notebook that the Observer called September has been keeping all these years on Fringe soon will be made available to us standard-issue humans — and TVLine has a sneak peek at his notes on one member of the team.

Penned by Tara Bennett and Paul Terry (who together compiled the official Lost Encyclopedia), Fringe: September’s Notebook merges exclusive photos and concept art with He Who Shall Become Known As Donald’s observed quirks and facts about each character from the about-to-end Fox drama. Below, we’ve got a look at the cover plus an exclusive preview of his pages on Astrid (click the thumbnail for a legible larger image).

September’s Notebook (out in March but available for pre-order) also offers insight into fringe science and promises to “uncover truths never before revealed.”
